Weather in December
Temperature
The warmest period is December, when temperatures fluctuate between an average high of 34.2°C (93.6°F) and a low of 22.6°C (72.7°F).Heat index
For December, the heat index is computed to be a torrid 38°C (100.4°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Be aware that heat index ratings are designed for shaded locations and minor breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. Increased relative humidity interferes with body cooling by slowing the rate of evaporation, resulting in a slower body cooling rate and a heightened feeling of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
